Использование дизель-генераторов в качестве общего или резервного источника питания является одним из наиболее удобных решений электроснабжения.. Но вас особенно беспокоит цена этих базовых конфигураций?? Слепо дешево покупать, жду, когда тебя можно будет использовать, когда всю дорогу бросишь.

При покупке дизельных генераторов необходимо сначала понять следующую конфигурацию, or you accidentally cheated!

1, see if the second-hand refurbished machine
There are some businesses to double the phone as a new machine sold to customers, there will be refurbished diesel engine coupled with a new generator and control cabinet, so that the general non-professional users simply can not tell whether the new machine or the old machine, which A little need to understand clearly.

2, confuse the relationship between KVA and KW
Not honest business will KVA as KW exaggerated power, sold to customers. In fact KVA is apparent power, KW is the effective power, the relationship between them is IKVA = 0.8KW. Import units generally use KVA that power units, and domestic power equipment are generally used KW said, so the accounting power should be KVA 8 fold converted into KW.

3, rated power and standby power relationship
Rated power and standby power can not be analogous because they are not the same “власть”, in fact, the standby power = 1.1x long line power. Более того, the standby power can only be used for 12 hours in continuous operation for 1 hour.

4, power configuration
Many diesel generators will be diesel engine power and generator power configured as large, in order to reduce costs. In fact, the industry generally provides diesel power ≥ 10% of the generator power, because there are mechanical losses. More harsh, and the diesel engine horsepower as a kilowatted false alarm to the user, and with less than the generator power of the diesel engine to configure the unit, commonly known as: small horses carts, as well as unit life, maintenance, High.

5, just talk about origin, do not speak brand
Merchants offer to customers is often only about origin, do not speak specific brands, in fact, the error inside is still very large. Such as Weifang diesel engine does not mean Weichai, Shanghai diesel does not represent the firewood, which the price difference between the great.

6, talk about diesel engines and generators only talk about the price
Talk about the diesel engine and generator brand grade, control system configuration, talk about after-sales service, blindly talk about the price and delivery time. Some will also be non-power station special oil machine, such as: marine diesel engine, vehicle diesel engine for generating units. So that the unit’s end product – electrical quality (voltage and frequency) can not be guaranteed.
